<h3 id="rationale">Rationale:</h3>
<p>ShellCheck found a command name that contains a <code>==</code>. Most
likely, this was intended as a kind of comparison.</p>
<p>To compare two values, use <code>[ value1 = value2 ]</code>. Both the
brackets and the spaces around the <code>=</code> are relevant.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>None, though you can quote the <code>==</code> to suppress the
warning.</p>
